Common mechanical cov khoom uas tau txiav txim siab hauv ntau cov khoom siv yog qhov tawv, toughness, lub zog, ductility, hardness, thiab cuam tshuam tsis kam.
Puas yog lub zog ntawm lub cev?
Lub cev muaj zog yog yam uas ntsuas tau. Cov no yog tej yam xws li ceev, melting point, conductivity, coefficient ntawm expansion, thiab lwm yam. Mechanical zog yog li cas cov hlau ua thaum sib txawv zog siv rau lawv. Uas suav nrog tej yam xws li lub zog, ductility, hnav tsis kam, thiab lwm yam.
Dab tsi yog cov khoom ntawm toughness?
Toughness yog cov khoom siv tseem ceeb ntsuas lub peev xwm ntawm cov khoom siv kom nqus tau lub zog thiab tiv taus kev poob siab txog kev tawg; uas yog, muaj peev xwm nqus tau lub zog hauv cov yas ntau.
Puas nyuaj yog lub cev lossis tshuaj lom neeg?
Ib lub cev khoom yog ib yam ntawm cov teeb meem uas tsis cuam tshuam nrog kev hloov hauv nws cov tshuaj muaj pes tsawg leeg. Cov piv txwv paub ntawm lub cev muaj zogsuav nrog qhov ntom ntom, xim, tawv, melting thiab boiling cov ntsiab lus, thiab hluav taws xob conductivity.
7 lub cev yog dab tsi?
Lub cev muaj xws li: tshwm sim, kev ntxhib los mos, xim, tsw, melting point, boiling point, ntom, solubility, polarity, thiab ntau lwm yam.
